发明名称 Elevatable display apparatus
摘要 A portable image projector is provided with a vertically elongated tower configuration to substantially reduce its vertical footprint when it is placed on a horizontal support surface for use. A stabilizing foot is positioned below the housing portion of the projector and is horizontally pivotable between a retracted orientation in which the foot is disposed within the vertical footprint of the projector housing, and an extended orientation in which the foot projects outwardly beyond opposite sides of the projector housing. The stabilizing foot is pivotally secured to the bottom ends of a spaced pair of arcuate elevating leg members that extend upwardly through openings in the bottom side of the housing. The leg members are vertically movable through the housing openings between retracted and extended positions and are resiliently biased in a downward direction relative to the housing. A latch mechanism releasably locks the legs in a selected vertical orientation and may be operated to selectively permit retraction or extension of the legs in a manner controllably adjusting the pivotal elevation of the lens portion of the projector.
